running the game for a few hours, & tried to colonise another planet but the ship refused to. Tried shutting game and reopening but the same thing happened. Clicked the upgrade button and the ship could once again colonise the planet. However the population was 0.01 (3 colony modules?). Also the modded colony ship I was using was travelling at 4pcs and the upgrade was 3pcs.
There is also a bug with AI planets, often when looking at the planet after conquest there are structures that if you click them can only be upgraded to soil enrichment ?
Over than that, good game. ( running latest beta, drivers etc )
